The Secret to Living Longer

Jogging is easy to do (at least in theory), and millions of people make it a daily or near-daily part of their exercise routine. In the past several decades, the number of jogging races and sheer numbers of joggers have increased dramatically, prompting this study on the potential long-term benefits of the popular activity. Published in the British Medical Journal, the study utilized data drawn from the Copenhagen City Heart Study on cardiovascular disease. Nearly five thousand men with no prior history of heart problems attended two examinations five years apart, at which time they were asked whether or not they jogged regularly.At the initial examination, 4.7% of the men said they jogged on a regular basis; 2.1% were still actively jogging five years later. In the five years between examinations, 2.3% of the study group started jogging. Men who reported jogging at both examinations had a substantially lower risk of death by any cause compared with men who reported jogging at neither or at only one examination.So lace up those shoes and begin the journey toward longevity today! A wealth of evidence supports the role of exercise in maintaining health and wellness. Make sure you and your loved ones participate in consistent, moderate exercise as part of a healthy, balanced lifestyle.

St. John's Wort: Effective Treatment for Depression

Written records document the use of Hypericum perforatum, otherwise known as St. John's wort, as early as the Middle Ages. Some accounts trace its use back to the ancient Greeks, who purportedly utilized extracts of the flowering plant as a treatment against demonic possession.Today, millions of depression sufferers are turning to St. John's wort to relieve their condition, and for good reason. Witness the results of a study that appeared in the September 2, 2000 issue of the British Medical Journal. Three hundred and twenty-four patients with mild-to-moderate depression received 250 mg of pharmacy-grade St. John's wort extract or 75 mg of imipramine, (one of the most commonly prescribed tricyclic antidepressants) twice daily.After six weeks of treatment, St. John's wort and imipramine were deemed equivalent in terms of their effect on depression symptoms, with a subscale of the depression rating scale indicating a significant advantage for St. John's wort. Patients also tolerated St. John's wort and reported fewer adverse reactions than patients taking the prescription medication. Some countries utilize St. John's wort to treat depression more frequently than other well-known depression medications such as Prozac, Paxil and Zoloft. As the results of this study suggest, they may be on to something. Talk to your doctor about the potential benefits of St. John's wort and other herbal extracts.Reference: Woelk H.

When Exercise Goes Away, Fat Comes to Stay

OK, let's figure out what's wrong with this picture: You come home from a long day's work, plop down on the couch, and spend the evening motionless save for the workout your fingers get flipping through stations with the remote. On a certain level, there's absolutely nothing wrong with the picture - you deserve to relax and recline after your daily labors. But if it becomes a nightly habit, you're probably not spending enough time on an important component of health and wellness: exercise.Considerable evidence points to consistent physical activity as a means of preventing obesity and its related complications, including type II diabetes, cardiovascular disease and high blood pressure. The exact cause of obesity remains elusive in the vast majority of cases, although the results of this study from the Annals of Internal Medicine point to inadequate exercise as a culprit.researchers examined 970 healthy female twins and found that physical activity (or lack thereof) predicted total-body and central abdominal fat. These results were maintained when considering other potential contributors to obesity, such as age, diet, smoking, socioeconomic status, and use of hormone replacement therapy (HRT). The authors also emphasized that these benefits were apparent even in subjects with a strong genetic preponderance toward obesity.Your doctor of chiropractic can provide you with more information on the benefits of consistent exercise and outline and diet and fitness regimen suitable to your needs.Reference: Samaras K, Kelly PJ, Chiano MN, et al.

Anger Predicts Coronary Artery Disease

It's never healthy to keep your stress bottled up inside, but all the evidence suggests that a slow simmer is almost always safer than a raging boil. Anger, especially anger manifested in bouts of uncontrollable rage or fury, can do serious damage - and not just to household items or innocent bystanders.The results of a study involving 12,986 men and women (45-64 years old at baseline) provide evidence that anger may predict coronary heart disease (CHD). As part of the Atherosclerosis Risk in Communities study, participants completed a trait anger scale assessing relative anger/rage; clinical examinations at baseline and follow-up assessed the incidence CHD and associated heart conditions.High levels of anger contributed to an increased risk of CHD and other coronary events, including acute myocardial infarction (MI) and fatal CHD. Specifically, the investigators noted a three times greater risk for people with the greatest difficulty controlling their anger compared to those with the least difficulty.The moral to this story: We all get frustrated and angry sometimes, but how we release or "control" our anger can make a big difference. It might mean the difference in staying healthy instead of suffering from heart disease. For more information, talk to your doctor.

Early Joint Trauma May Lead to Osteoarthritis

Osteoarthritis is the most common form of joint disease, and numerous factors can contribute to its development, including general "wear and tear" and family history of the condition. Osteoarthritis is fairly common in the elderly population, although it can also strike younger people. Evidence now suggests that joint trauma in childhood or young adulthood may contribute to osteoarthritis in later life. A recent study in the Annals of Internal Medicine recorded prior and current injury status in 1,321 young medical students (average age: 22 years). Injury was defined as trauma to the knee or hip joint. Subsequent trauma and specific sites of arthritis were reported during a 36-year follow-up period. Nearly 14% of participants who reported a knee injury in youth or young adulthood developed osteoarthritis of the knee by age 65, compared with only six percent of those without any such prior injury. Overall, prior joint injury significantly correlated with risk for later-life osteoarthritis at the specific injury site. The authors urge the use of proper sports equipment under safe conditions to help prevent joint injuries in youth.

Breastfeeding Reduces Childhood Asthma Risk

Asthma is the most common chronic respiratory disease to affect children (an estimated 7-10% of the pediatric population). Various environmental and maternal factors have been suggested as possible causes, but what about the solution to this frustrating condition? A recent study published in the Journal of Asthma found that breastfeeding can reduce the risk of children developing asthma. Among nearly 5,200 Brazilian schoolchildren 7-14 years of age, children who had not been breastfed during infancy were more likely to suffer from asthma, wheeze (labored breathing, particularly when exhaling, sometimes accompanied by tightness in the chest), or wheeze after exercise compared with children breastfed for six months or more. This association was noted only in children without a family history of asthma, emphasizing the independent protective influence of breastfeeding on asthma risk. These findings add to the considerable evidence linking breastfeeding with positive health benefits for the child.

The Road to Regulating Blood Pressure During Pregnancy

The benefits of exercising during pregnancy include shorter labor and timely delivery; higher birth weight babies; and reductions in nausea, fatigue and other pregnancy-related discomfort. Add regulating blood pressure to this list, according to a study published in the Journal of Reproductive Medicine. Sixteen expectant mothers were recruited for the study before 14 weeks of gestation, observed for four weeks, then assigned to an exercise or a control group. The exercise group performed 30 minutes of moderate-intensity exercise, consisting of activity on a motorized treadmill or bicycle ergonometer, three times a week for 10 weeks. The control group maintained individual levels of physical activity. Systolic blood pressure did not change significantly in either group, but diastolic blood pressure decreased in the exercise group and increased slightly in the control group. Both groups engaged in similar levels of daily physical activities and were similar with respect to weight and body composition, suggesting that the added exercise sessions exerted an independent influence on blood pressure.

Lower Your Cholesterol with Macadamia Nuts

Heart disease is all-too-common, especially in the United States. Although there's a definite tendency for heart disease to run in families, lifestyle factors such as diet, smoking and stress also play a substantial role. Dietary practices have long been linked to heart disease, especially the consumption of foods that help lower cholesterol levels. A study published in the Archives of Internal Medicine evaluated the cholesterol-lowering ability of macadamia nuts in 30 volunteers, aged 18-53. Subjects consumed three specific diets in random order: a "typical American diet," with 37% of energy derived from fat; an American Heart Association "Step 1" diet, with 30% of energy from fat; and a macadamia-nut based diet, with 37% of energy derived from primarily monounsaturated fat. After one month, cholesterol levels were lower in the group consuming the macadamia nut diet, compared with the other two groups. The typical American diet proved the least effective of the three diet plans in lowering cholesterol. No significant side effects were noted from ingesting large quantities of macadamia nuts, leading the authors to conclude: "Physicians can recommend the consumption of these and other nuts as part of a satisfying and healthy diet."
